Introduction
Overview
The OMG-PCI-DIO48 provides two 8255 mode 0 compatible ports providing
four eight-bit ports and four four-bit ports. Each can be individually configured
as inputs or outputs. When configured as outputs each bit of the four bit ports
may be set or reset individually.
What’s Included
The OMG-PCI-DIO48 is shipped with the following items. If any of these items
is missing or damaged, contact the supplier.
•

•
OMG-PCI-DIO48 Adapter
Software
Industry Standard Relay Rack Cables are Available:
Part number CA135 for Edge Connection
Part number CA167 for IDC Connection
Installation
Card Setup
The OMG-PCI-DIO48 is a fully compliant PCI ‘Plug and Play’ adapter. All card
resources (i.e. I/O address, IRQ selection) are auto-assigned by either your
system BIOS or your ‘Plug and Play’ operating system.
Software Installation
For proper operation install software first. To install the software place the CD in
your CD-ROM tray and the auto-run program will start. If auto-run is not
available browse the CD and choose “index.htm”. Choose Install Software at the
beginning of the CD. Select the Digital I/O software drivers and install SeaIO
prior to installing hardware.
Linux Users
Refer to the installation instructions at the beginning of the CD for details on
installing the digital I/O cards in Linux.

Technical Description
Technical Description
The OMG-PCI-DIO48 provides 48 channels of digital I/O configurable as inputs or outputs, which
can be utilized for PC based control and automation including sensors, switches, satellite antenna
control systems, video and audio studio automation, security control systems, and other industrial
automation systems.
Software
The OMG-PCI-DIO48 ships with the SeaI/O suite of Windows 98/NT/ME/2000 drivers. SeaI/O
provides the user with a consistent and straightforward API, allowing the developer to concentrate
on the details of the application as opposed to low level driver development. Popular development
environments, including Visual C++, Visual Basic, and Delphi, are supported for application
development. SeaI/O includes a utility for configuring the driver parameters under Windows,
further simplifying installation.
Linux Users
The OMG-PCI-DIO48 ships with software for Linux, including a kernel-mode driver, API, and the
SeaIOTst diagnostic tool. The kernel-mode driver is provided as a module, so future driver
upgrades may be performed with minimal (usually zero) downtime. The Linux API is identical to its
Windows counterpart, facilitating quick and easy ports of existing SeaI/O-aware applications to the
Linux operating system. All source code for the Linux software suite is provided under the GNU
Public License (GPL v2.0), to assist in "roll-your-own"-type applications.

Technical Description
Pull Ups
Ten pin bussed resistor packs are installed to provide pull-ups to the input ports. These are
installed on all ports. The pull-up resistor packs are rated at 10K ohms. Figure 2 below provides the
bussed resistor and corresponding port. The resistors insure that no line is floating which is not
connected. This provides consistent biasing on all un-terminated lines.

Technical Description
Application Programmers Interface (API)
Most modern operating systems do not allow direct hardware access. The SeaIO driver and API
have been included to provide control over the hardware in Windows and Linux environments.
The purpose of this section of the manual is to help the customer with the mapping of the API to
the actual inputs for the 8005 specifically. Complete documentation of the API can be found in its
accompanying help file.
Presetting an Output Port:
Each port has an output register associated with it. This register may be written and retains its
value whether the port is configured as an input or an output. To preset the value of an output port
the program should write to the port when it is configured as an input then configure it as an
output. Inputs cannot be written to with relative addressing, absolute addressing must be used.
See Relative Addressing vs. Absolute Addressing below.
Interrupts:
Interrupt sampling can be set up in the API. Port A1 bit zero is the interrupt source (pin 47). Refer
to the API section in the SeaI/O help file for more detailed information.
Port C
Port C of each bank has the ability to be configured as two four bit ports. If both lower and upper
nibbles are configured the same then no special considerations need to be made. But if they are
configured differently, one nibble as input, and one as output then the user will have to keep this in
mind.
Port C absolute addressing (when port C is split)
When reading, the input nibble will be returned on the corresponding upper or lower
nibble while the outputs will be returned on their corresponding upper or lower nibble.
When writing, the corresponding nibble will be written to the output nibble, while the
input nibble will have its output register written to. The output register can be written to
without affecting the inputs. These will be eight bit operations and it will up to the
programmer to keep track of the two four bit nibbles.
OMG-PCI-DIO48
Page 8
Technical Description
Port C relative addressing (when port C is split)
The input and output nibbles will each be treated as individual four bit ports.
Port Configuration:
Each eight-bit port can be configured as inputs or outputs. The API provides a set adapter state
call to access the control words. For this device, two control word is used. Refer to the following
table.
Note: : The control panel also allows you to configure the device. Your program can over ride the
control panel configuration when executed, but the control panel configuration will be the default
on power up. The default settings are based on the settings in the control panel application when
last changed and saved after re-booting.

Relative Addressing vs. Absolute Addressing
The SeaIO API makes a distinction between “absolute” and “relative” addressing modes. In
absolute addressing mode, the Port argument to the API function acts as a simple byte offset from
the base I/O address of the device. For instance, Port #0 refers to the I/O address base + 0; Port #1
refers to the I/O address base + 1.
Relative addressing mode, on the other hand, refers to input and output ports in a logical fashion.
With a Port argument of 0 and an API function meant to output data, the first (0th) output port on
the device will be utilized. Likewise, with a Port argument of 0 and an API function designed to
input data, the first (0th) input port of the device will be utilized.
In all addressing modes, port numbers are zero-indexed; that is, the first port is port #0, the second
port is #1, the third #2, and so on.

Direct Hardware Control
In systems where the users program has direct access to the hardware (DOS) the tables below
gives the mapping and functions that the 8005 provide. The address of each eight-bit port is
calculated as shown in the table on the following page, the cards base address plus an offset.
Reading the Inputs:
The inputs are active high. If an input is driven high (2V to 5.25 V) it will read as a logical one (1), if
driven low (0V to 0.8V) it will read as a logical zero (0). If an input is not driven it will read as a one
due to the 10K ohm pull up resistors on each port.
Reading the Outputs:
The value that is currently being used to drive the outputs will be returned.
Presetting an Output Port:
Each port has an output register associated with it. This register may be written and retains its
value whether the port is configured as an input or an output. To preset the value of an output port
the program should write to the port when it is configured as an input then configure it as an
output.
Writing the Outputs:
The outputs are active high. Writing a one (1) corresponds to 5V while writing a zero (0)
corresponds to 0V, at the output.
Bit Set/Reset
Port C supports bit set/reset as shown in the tables below.
Port Configuration:
Each port can be configured as an input or an output by writing to its direction control bit, refer to
the tables below.

Interrupts
Interrupts can be set up as shown in the tables on the next page.

Technical Description
Port C
Port C is written and read to as a single eight bit port, but it has the ability to be configured as two
four bit ports. If both lower and upper nibbles are configure the same then no special
considerations need to be made. But if they are configured differently, one nibble as input, and one
as output then the user will have to keep this in mind. When reading, the input will be returned on
the corresponding upper or lower nibble while the current outputs will be returned on their
corresponding upper or lower nibble. When writing, the corresponding nibble will be written to the
output nibble, while the input nibble will have its output register written to. The output register
can be written to without affecting the inputs.
